Multiple emission energies in single-photon emission computed tomography

摘要

Single photon emission computed tomography (SPECT) is performed with multiple emission energies. For the quantitative or qualitative SPECT, the imaging process for emissions in different energy ranges is modeled separately (44, 46, 48, 50). Different scattering, different attenuation and / or different collimator-detector-response models corresponding to different energy ranges are used in the reconstruction.
